Hi, I went on trying:
....Then removing deprecated binary_function following this page helped me clear
the next issue:
https://stackoverflow.com/questions/22386882/why-have-unary-function-binary-function-been-removed-from-c11
So in compare_pointees.hpp line 36 may become:

struct equal_pointees_t {
  bool operator() ( OptionalPointee const& x, OptionalPointee const& y ) const
    { return equal_pointees(x,y) ; }
  typedef OptionalPointee first_argument_type;
  typedef OptionalPointee second_argument_type;
  typedef bool result_type;
} ;


And line 61:

struct less_pointees_t {
  bool operator() ( OptionalPointee const& x, OptionalPointee const& y ) const
    { return less_pointees(x,y) ; }
  typedef OptionalPointee first_argument_type;
  typedef OptionalPointee second_argument_type;
  typedef bool result_type;
} ;

However in function _template.hpp, line 662 should also change:
    , public std::function<T0,R>
and line 666:
    , public std::function<T0,T1,R>
but to what?


(using CLANG-cl compiler in MSVS2019 from its internal installer, and ISO C++ 17
language version
